ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 318,291, dated May 19,1885 Application filed July 30, 1884. (No model.)

To ali whom, it may concern.-

Be it known that I, CADWALLADER M. RAY- MOND, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented a new and useful Improvement inRoller-Skates, of which the following is a specification.

My invention relates to certain improvements in roller'-skates,wherebyan elastic bearing is provided for the heel and toe plates. An improvedmeans is also provided for adjusting the tension of the elastic bearing,together with other improvements, more fully hereinafter set forth, andpointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of a roller-skateembodying my improvements. Fig. 2 is a top view of the same. Fig. 3 is ayiew of the under side of the skate. Fig. 4 is a vertical section of thehanger, the elastic cushion, and attachments, the parts being shown asseparated. Fig. 5 is a transverse vertical section of the same, theparts being connected together. Fig. 6 represents the elastic cushion.Fig. 7 represents the adjusting device.

The main features of the skate are fully .described in my Patent No.313,622, and so need not to be described in detail.

A and B are respectively the toe. and heel plates, the toe-plate A beingbent at the point d, and having a slot through which the forward part ofthe heel-plate B passes, and thence between a frame riveted to the underside of the toe-plate, and the toe-plate. The toe-plate passes in asimilar manner under the heel-plate, and between it and a frame thatcarries the hanger and elastic cushion.

At the rear of the heel-plates are the clamps b b, forming a portion ofthe heel-plate, and are bent upward and over inwardly at the upper ends,so as more securely to hold the heel portion of the boot or shoe.

In the heel-plate is an elongated slot of equal width throughout itslength, and in this slot is fitted a slotted plate,'lE[, which is bentupward at the rear end and projects to the rear, as shown in Fig. 1, soas to clamp the boot or shoe heel. It is capable of being adjusted tothe size of the heel, and is held in position by means of the screw Gand nut I.

G is a bent lever, pivoted to the heel-plate B atthe point D, and at thebent portion-F of the said lever is pivoted a flat bar, E, through theother end of which latter passes the screwbolt G. The said screw-boltalso passes through the slotted plate H and through one of the holes, a,in the extended portion of the toe-plate A, and is secured by the nut I.

The holes a in the heel-plate B are not entirely circular, but have asegment removed at one side. as shown in Figs. 2 and 3, and the side ofthe screw G is of corresponding shape in section, so that when the screwis inserted in the holes 0 the segmental portion of the screw will bearagainst the corresponding segment of the holes 0, and thus prevent thescrew from turning-a difficulty that is liable to occur in the constantuse of the skate.

The plate H and bar E and the toe and heel plates A B are securedtogether by means of the screw and thumb-nut G and I.

To the under side of the toe and heel plates A B are secured the framesL L, which are so constructed as to leave a space between them and theunder side of the toe and heel plates, so as to allow the narrowportions of the said plates to pass freely through the said spaces. Onthe under side of the center of the plates L are studs or teats Z, asshown in Figs. 4 and 5. The central recessed portions of the plates Lincline longitudinally from the outer ends, as indicated in Fig. 4. Atthe outer end of each plate L is a short bracket, N, forming a loop, andat the inner end of each plate is a forked bracket, M, having at itsupper end a projection, m, having a hole through it. Qis a hanger havingon its upper ends the bearings q q, and provided with a centrallongitudinal rib or projection on its upper side. 0 is an elasticcushion or spring, as shown in Fig. 6. The lower side is made taperingor beveled, and is provided with a central groove, which fits upon therib on the upper part of the hanger Q. On the upper side of the spring 0is a central depression, in which fits the stud Z on the under side ofthe plate L, as shown in Fig. 5. The spring 0 is placed between theframe L and the hanger Q, and is held in position by means of the grooveand depression fitting, respectively, the rib on the hanger and the studZ on the plate L. The

hearing qof thehanger Q is fitted in the bracket N and the bearing q inthe forked brackeh M- R is a screw-bolt having an eye or opening,

.1, at one end, which fits loosely upon the toe-and heel platesvertically as well as later-' 'ally, and thus relieving the wearer ofany unpleasant jarring occasioned by passing over any-uneven surface orobstacle.

What I claim as my invention is a 1. The frame L, provided with thebrackets MI N in combination with the hangerQ, providediwith thebearingsq q, the screw-bolt R, having eye-r, to receivethe bearing g, and nutU,and theelastic cushion Q, asand for the purpose set forth.

2. The screw-bolt R, having eye 1* and nut U, the hanger Q, havingbearings q q, and the frame L, having bracket N, open bracket M,

and projection on, all combined and operating as and for the purpose setforth.

3. The combination, with the plate L, having the central projection, l,of the tapering cushion 0, provided with a central depression .in oneside and a groove in the other side, and

the hanger Q, having a rib upon its upper fiat surface" to enter thegroove in the cushion, substantially as described.

In testimony whereof Ihave signed my name to this specification inthepres'en-ce of two'subscribing WIl'JHGSS GS.
